AUTOMATIC eeviiiiiioii Application filed November Y5, SeriaIVN-QQQYJEQ.

Thisinvention relates to an antomatic governorand as illustrated anddescribed herein, it is particularly adapted for use, for controllingthetime of ignition in an internal that the spark ade vance should besubstantially coincident with the increase in the Speed o the engine,and contrarirvise shonld ybedeerease:d with a de crease in speed of theengine. It is pracf tically impossible to get proper mannal control ,ofthe ignition spark, control. I

lllyfinvention is therefore directed to iinprovements in automaticgovernors for nit-ion spark control. Y Y Y ln various `devices of theprior art, with Weich I am familiar, it is the nsnalpractiee to pivottheweights or Weir ated arms at one end, such .for example asillnstrated in the Vllioore PatentrlSSJFi, issued August 23rd, 1921? butl have found that such an arrangement reduces the eli'ective force ofthe Weights, that is to say, those portions ot the Weights near thepivot points produce but little effect, as will be apparent from a studyof such air arrangement. Y

Another objection which I have found to a structure similar to thatshown inthe said I" isfivell understood ltloore atent is that the endsof lthe Weifrhts i p 7 i i C) 5 being some distance from the pivotpoints areapt to flop` back and forth at low speed, striking the vdrivenmember, and thereby producing a noise. i

Aistill turth r'objection to a' governor of thcftype disclosed in saidMoore patent, is that it is not strictly interchangeable for differentdirectionsot' rotation ofthe operating snat't, th at is to say, if it isdesired to rotate a governor of the Moore type opposite in directionfrom that first intended, the weights must be assembledV in reverseAposition in `order to get good ooperation..v

One of .the'objectsl of my invention is to provide a governor for thepurpose herein described, inwhich the Weights -are substantially equallybalanced ,on a central median line, whereby the centrifugal Aforce actsimi-A Vtormly on all parts of the Weight.

Another object of my invention is toV provide a governor which Willoperate vequally )yell in either direction or" rotation, Witlioiit lshifting the position of any of the parts.

Another obgect of my invent-ion is to pro-f governor in which thefriction ,1S fiberv oecd a mininlinn.l

stem 5 Iis preferably tapered Vto receive the 5 tapered end iof *of theignition` unit7 such as a magneto. 'A nnt`7`sho'wn' inFig-. nre lOfbeingprovided to `Within the `bore 8, oft the driven i Glan beine* thread'-ico shaft of the ignition unit. A keyivay 10, is provided vin the stem5, and as the end 11, of the nut 7, comes against the angular shoulder12, Vdriven member 6, is drawn into rm engagement With the shaft of theignition unit.

The member 1, is provided on its inner surface With flanges 13, whichextend clear across the inner face thereof thereby forming a groove orguideway 14. Y

Positioned across the flanges 13, and substantially symmetricallydisposed with rel spect thereto are a pair of Weights 15 and 16; theseWeights are preferably made upl of three punchings fastened together asby means of rivets 17. The middle lamination is cut away at its centralportion, as indicated by the dotted line 18, to provide clearance forone end of link 19, Which has a pivot pin 20, preferably immovablyfastened thereto, so that the ends of the pinsy have a bearing in thetop and bottom pieces comprising the Weights 15 and 16, all as clearlyshown in Figure 3. The pivot pin 20, eX- tends beyond the Weight 15 intothe groove 14, and carries a roller 21, thereon, Which is likely to movevup and down in the groove or guideway 14, in engagement With the sidesof the flanges 13, as the Weights 15 and 16 respond to centrifugalforce. The middle lamination of Weights 15 and 16 has extensions intheform of hooks 22, and these adjacent projections or hooks are engaged bysprings 23, and 24, whereby the Weights are heldin retard position asshown in Figure 1. The inner ends of the links 19, are pro-Y vided'withpivot pins 25, that are preferably immovably attached to the links, `butthe ends of the pivot pins 25, are movable in the holes 26 ofthe lugs orlears 27, which extend from the driven member 6. rIn order to eliminateor reduce to a minimum any noise which the Weights might produce onreturning suddenly to retard position, I provide thev driven memberWith' bumpers 28, of vsome suitable material, such as fibre or rawhide,on Which the Weights rest in retard position.

Since a complete housing for the driven member 6, is provided by theparts 1 and 2, a drivin connection must be made to the casing, Vt is isdone through the mediuln of a plurality of studs 29, three being shownin Figure 5. The studs 29 are fastened to the cover in any satisfactorymanner. Likewise the cov-er is held to the rigid member 1, by a pair ofstuds 30, Which pass through the holes 31,V as Will be seen from Figures5, and 6, and 7. It is to be understood that a suitable coupling memberis adapted to engage the studs 29, to drive the governor and theignition shaft.

The governor so far'described Will produce substantially a straight linecurve, but for certain requirements this straight line curve requires tobe modified and this modification can be brought about, by the use of anauxiliary spring associatedwith the Weights. For this purpose Ivpreferto use a flat spring 32, Which may be att-ached to the Weights inany satisfactory manner, that shown in the drawing comprises a flatsurface in the outer part of the weights on which the `flat spring 32,rests; thesprings are held in position by peening over the metal asshown in Figure 3. It Will be understood that Vthe springs 32 are ofsuitable thickness and quality to give the desired modification to thespark advance curve as the ends of the springs 32 engage the inner Wallof the rim or cover 2, when the vWeights move away from the center.

In place of the hooks shown in Figures 1, and 2,'the central laminationof the Weights may be constructedwith eyelets 33, as shown in Figure 4.Y Y

The operation of my device will be apparent Without any 'extendeddescription thereof, but it'may be pointed out, that the Weights are sopositioned over thenarrov flanges 13, as to produce little friction, andthe Weights'are so disposed as to be acted on uniformly by centrifugalforceV and consequentiy they move in a lateral direction from the drivenmember, beingguided by the rollers 21, operating in the gudeway 14. Asthe Weights 15 and 16 move outwardly toward the rim of the cover 22,under the action of centrifugal force the driven memberr 6, is shiftedinrposition or advanced so as toV advance the time of the spark producedin the engine cylinders. 'The auxiliary spring 32 as has been pointedout, is arranged of suitable thickness and length and material as tomodify the speed of rotation ofthe given member as desired, to producethe necessary spark curve.

It will also be apparent that the governor canbe operatedVV ineitherdirection of rotation Without any change in position of Vtheweights orv their associated members. Furthermore the pivot pinsassociated with the links being fastened rigidly to the links and havingbearings on Vboth sides of the links, Agives a structure insuringlongservice for these parts. A

It Will be apparent that various changes may be made in the detailscomprising the governor herein described and I therefore do not Wish tobe unduly limited in the interpretation of the appended claims.
